A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

• Switching over to California drought tolerant low water plants
• Installation of low flow/water drip systems and smart irrigation controllers
• Replace ornamental lawns with drought resistant plants, shade trees, decomposed pathways, and intimate seating areas (benches, tables, and chairs).
• Discontinue exterior power washing methods with dry sweeping and area spot cleaning as needed
